Jewish ethnic divisions

Jewish ethnic divisions refers to a number of distinct communities within the world's ethnically Jewish population. Although considered one single self-identifying ethnicity, there are distinct ethnic divisions among Jews, most of which are primarily the result of geographic branching from an originating Israelite population, and subsequent independent evolutions.[1]

As long ago as Biblical times, cultural and linguistic differences between Jewish communities, even within the area of Ancient Israel and Judea, are observed both within the Bible itself as well as from archeological remains. In more recent human history, an array of Jewish communities were established by Jewish settlers in various places around the Old World, often at great distances from one another resulting in effective and often long-term isolation from each other. During the millennia of the Jewish diaspora the communities would develop under the influence of their local environments; political, cultural, natural and populational. Today, manifestation of these differences among the Jews can be observed in Jewish cultural expressions of each community, including Jewish linguistic diversity, culinary preferences, liturgical practices, religious interpretations, as well as degrees and sources of genetic admixture.

Historical background

Ancient Israel and Judah

The full extent of the cultural, linguistic, religious or other differences among the Israelites in antiquity is unknown. Following the defeat of the Kingdom of Israel in the 720s BCE and the Kingdom of Judah in 586 BCE, the Jewish people became dispersed throughout much of the Middle East, especially in Egypt and North Africa to the west, as well as in Yemen to the south, and in Mesopotamia to the east. The Jewish population in Palestine was severely reduced by the Jewish-Roman Wars and by the later hostile policies of the Christian emperors,[2] against non-Christians, but the Jews always retained a presence in Palestine. During this period, Paul Johnson writes: "Wherever towns survived, or urban communities sprang up, Jews would sooner or later establish themselves. The near-destruction of Palestinian Jewry in the second century turned the survivors of Jewish rural communities into marginal town-dwellers. After the Arab conquest in the seventh century, the large Jewish agricultural communities in Babylonia were progressively wrecked by high taxation, so that there too the Jews drifted into towns and became craftsmen, tradesmen, and dealers. Everywhere these urban Jews, the vast majority literate and numerate, managed to settle, unless penal laws or physical violence made it impossible."[3]

In the early-Byzantine 6th century, there were 43 Jewish communities in Palestine. During the Islamic period and the intervening Crusades, there were 50 communities which included Jerusalem, Tiberias, Ramleh, Ashkelon, Caesarea, and Gaza. During the early Ottoman Period of the 14th century there were 30 communities which included Haifa, Shechem, Hebron, Ramleh, Jaffa, Gaza, Jerusalem, and many in the north. The most dominant location became Safed which reached a population of 30,000 Jews by end of the 16th century, after the expulsion of Sephardim from Iberia, a century earlier. Johnson notes that in the Arab-Muslim territories, which included most of Spain, all of North Africa, and the Near East south of Anatolia in the Middle Ages, the Jewish condition was easier as a rule, than it was in Europe.[4]

Over the centuries following the Crusades, Jews from around the world began emigrating in increasing numbers. Upon arrival, these Jews adopted the customs of the Mizrahi and Sephardi communities into which they moved. With Baron von Rothschild's philanthropic land purchases and subsequent efforts to turn Palestine into a verdant Jewish homeland, and the subsequent rise of Zionism, a flood of Ashkenazi immigration brought the Jewish population of the region to several hundred thousand.

Diaspora

Following the loss of their second revolt against the Romans and their exile by them, at the height of the empire in the 2nd century, Jewish communities similarly could be found in nearly every notable center throughout it, as well as scattered communities found in centers beyond the Empire's borders in northern Europe, in eastern Europe, in southwestern Asia, and in Africa. Farther to the east along trade routes, Jewish communities could be found throughout Persia and in empires even farther east including in India and China. In the Early Middle Ages of the 6th to 11th centuries, the Radhanites traded along the overland routes between Europe and Asia earlier established by the Romans, dominated trade between the Christian and the Islamic worlds, and used a trade network that covered most areas of Jewish settlement.

In the middle Byzantine period, the khan of Khazaria in the northern Caucasus and his court converted to Judaism, partly in order to maintain neutrality between Christian Byzantium and the Islamic world. This event forms the framework for Yehuda Halevi's work 'The Kuzari' (c.1140), but how much these traces of Judaism within this group survived the collapse of the Khazar empire is a matter of scholarly debate.

In western Europe, following the collapse of the Western Roman Empire in 476, and especially after the re-orientation of trade caused by the Moorish conquest of Iberia in the early 8th century, communications between the Jewish communities in northern parts of the former western empire became sporadic. At the same time, rule under Islam, even with dhimmi status, resulted in freer trade and communications within the Muslim world, and the communities in Iberia remained in frequent contact with Jewry in North Africa and the Middle East, but communities further afield, in central and south Asia and central Africa, remained more isolated, and continued to develop their own unique traditions. For the Sephardim in Spain, it resulted in a "Hebrew Golden Age" in the 10th to 12th centuries.[5] The 1492 expulsion from Spain by the Catholic Monarchs however, made the Sephardic Jews hide and disperse to the Netherlands and other existing communities in Christian Europe, to within the Ottoman Empire, to the Maghreb in North Africa and smaller numbers to other areas of the Middle East, and eventually to the Americas in the early 17th century.

In northern and Christian Europe during this period, financial competition developed between the authority of the Pope in Rome and nascent states and empires. This dynamic, with the Great Schism, recurrent fervid anti-Christian religious Crusades, and later protestations and wars between Christians themselves, caused repeated periods and occurrences of persecution against the established Jewish minority in "Ashkenaz"—that is, the areas that are now northern France and Germany—masses of Jews began to move further to the east. There, they were welcomed by the king of Poland,[6] and with Lithuania, grew greatly, and relatively flourished to the end of the 18th century. In western Europe, the conditions for Jewry differed between the communities within the various countries and over time, depending on background conditions. With both pull and push factors operating, Ashkenazi emigration to the Americans would increase in the early 18th century with German-speaking Askenazi Jews, and end with a tidal wave between 1880 and the early 20th century with Yiddish-speaking Ashkenazim, as conditions in the east deteriorated under the failing Russian Empire. With the Holocaust and the destruction of most European Jewry, North America would hold the majority of world Jewry.

Modern divisions

Historically, Jews have been identified into two major groups: the Ashkenazim, or "Germanics" ("Ashkenaz" meaning "Germany" in Medieval Hebrew, denoting their Central European base), and the Sephardim, or "Hispanics" ("Sefarad" meaning "Hispania" or "Iberia" in Hebrew, denoting their Spanish and Portuguese base). The far more recent term Mizrahim, or "Easterners" ("Mizrach" being "East" in Hebrew) to include Middle Eastern and North African Jews, constitutes a third major group to some, following the partition of Palestine, their often-forced migration, and the re-establishment of their communities in Israel.

Smaller Jewish groups include the Georgian Jews and Mountain Jews from the Caucasus; Indian Jews including the Bene Israel, Bnei Menashe, Cochin Jews and Bene Ephraim; the Romaniotes of Greece; the ancient Italian Jewish community; the Teimanim from the Yemen and Oman; various African Jews, including most numerously the Beta Israel of Ethiopia; the Bukharan Jews of Central Asia; and Chinese Jews, most notably the Kaifeng Jews, as well as various other distinct but now extinct communities.

The divisions between all these groups are rough and their boundaries aren't solid. The Mizrahim for example, are a heterogeneous collection of North African and Middle Eastern Jewish communities which are often as unrelated to each other as they are to any of the earlier mentioned Jewish groups. In modern usage, however, the Mizrahim are also termed Sephardi due to similar styles of liturgy, despite independent evolutions from Sephardim proper. Thus, among Mizrahim there are Iranian Jews, Iraqi Jews, Egyptian Jews, Tunisian Jews, Algerian Jews, Moroccan Jews, Lebanese Jews, Kurdish Jews, Libyan Jews, Syrian Jews, and various others. The Yemenite Jews ("Teimanim") from Yemen and Oman are sometimes included, although their style of liturgy is unique and they differ in respect to the admixture found among them to that found in Mizrahim. Additionally, there is a difference between the pre-existing Middle Eastern and North African Jewish communities as distinct from the descendants of those Sephardi migrants who established themselves in the Middle East and North Africa after the expulsion of the Jews from Spain by the Catholic Monarchs in 1492, and a few years later from the expulsion decreed in Portugal.

Despite this diversity, Ashkenazi Jews represent the bulk of modern Jewry, estimated at between 70% and 80% of all Jews worldwide;[7][8] prior to World War II and the Holocaust however, it was 90%.[7] While Ashkenazim developed in Europe, their massive emigration from Europe for better opportunities, and during periods of civil strife and warfare, they also became the overwhelming majority of Jews in the New World continents and countries, which previously were without native European or Jewish populations. These include the United States, Canada, United Kingdom, Argentina, Australia, Brazil and South Africa, but with Venezuela and Panama being exceptions since Sefaradim still compose the majority of the Jewish communities in these two countries. In France, more recent Sephardi Jewish immigrants from North Africa and their descendants now outnumber the pre-existing Ashkenazim. Only in Israel is the Jewish population representative of all groups, a melting pot independent of each group's proportion within the overall world Jewish population.

Genetic studies of DNA

Despite the evident diversity displayed by the world's distinct Jewish populations, both culturally and physically, genetic studies have demonstrated most of these to be genetically related to one another, having ultimately originated from a common ancient Israelite population that underwent geographic branching and subsequent independent evolutions.[9]

A study published by the National Academy of Sciences stated that "The results support the hypothesis that the paternal gene pools of Jewish communities from Europe, North Africa, and the Middle East descended from a common Middle Eastern ancestral population, and suggest that most Jewish communities have remained relatively isolated from neighboring non-Jewish communities during and after the Diaspora."[9] Researchers expressed surprise at the remarkable genetic uniformity they found among modern Jews, no matter where the diaspora has become dispersed around the world.[9]

Moreover, DNA tests have demonstrated substantially less inter-marriage in most of the various Jewish ethnic divisions over the last 3,000 years than in other populations.[10] The findings lend support to traditional Jewish accounts accrediting their founding to exiled Israelite populations, and counters theories that many or most of the world's Jewish populations were founded by entirely gentile populations that adopted the Jewish faith, as in the notable case of the historic Khazars.[10][11] Although groups such as the Khazars could have been absorbed into modern Jewish populations — in the Khazars' case, absorbed into the Ashkenazim — it is unlikely that they formed a large percentage of the ancestors of modern Ashkenazi Jews, and much less that they were the genesis of the Ashkenazim.[12]

Even the archetype of Israelite-origin is also beginning to be reviewed for some Jewish populations amid newer studies. Previously, the Israelite origin identified in the world's Jewish populations was attributed only to the males who had migrated from the Middle East and then forged the current known communities with "the women from each local population whom they took as wives and converted to Judaism".[13] Research in Ashkenazi Jews has suggested that, in addition to the male founders, significant female founder ancestry might also derive from the Middle East, with about 40% of the current Ashkenazi population descended matrilineally from just four women, or "founder lineages", that were "likely from a Hebrew/Levantine mtDNA pool" originating in the Near East in the 1st and 2nd centuries CE.[13]

Points in which Jewish groups differ is largely in the source and proportion of genetic contribution from host populations.[14][15] As examples, the Teimanim differ from other Mizrahim, as well as from Ashkenazim, in the proportion of sub-Saharan African gene types which have entered their gene pools.[14] Among Yemenites, the average stands at 35% lineages within the past 3,000 years.[14] Yemenite Jews, as a traditionally Arabic-speaking community of local Yemenite and Israelite ancestries,[15] are included within the findings, though they average a quarter of the frequency of the non-Jewish Yemenite sample.[14] In Ashkenazi Jews, the proportion of male indigenous European genetic admixture amounts to around 0.5% per generation over an estimated 80 generations, and a total admixture estimate around 12.5%.[9] The only exception to this amongst Jewish communities is in the Beta Israel (Ethiopian Jews); a 1999 genetic study came to the conclusion that "the distinctiveness of the Y-chromosome haplotype distribution of Beta Israel Jews from conventional Jewish populations and their relatively greater similarity in haplotype profile to non-Jewish Ethiopians are consistent with the view that the Beta Israel people descended from ancient inhabitants of Ethiopia who converted to Judaism."[16][17] Another 2001 study did, however, find a possible genetic similarity between 11 Ethiopian Jews and 4 Yemenite Jews from the population samples.[18]

DNA analysis further determined that modern Jews of the priesthood tribe — "Cohanim" — share a common ancestor dating back about 3,000 years.[19] This result is consistent for all Jewish populations around the world.[19] The researchers estimated that the most recent common ancestor of modern Cohanim lived between 1000 BCE (roughly the time of the Biblical Exodus) and 586 BCE, when the Babylonians destroyed the First Temple.[20] They found similar results analyzing DNA from Ashkenazi and Sephardi Jews.[20] The scientists estimated the date of the original priest based on genetic mutations, which indicated that the priest lived roughly 106 generations ago, between 2,650 and 3,180 years ago depending whether one counts a generation as 25 or 30 years.[20]

Geographic distribution

Because of the independence of local communities, Jewish ethnicities, even when they circumscribe differences in liturgy, language, cuisine and other cultural accoutrements, are more often a reflection of geographic and historical isolation from other communities. It is for this reason that communities are referred to by referencing the historical region in which the community cohered when discussing their practices, regardless of where those practices are found today.

The smaller groups number in the hundreds to tens of thousands, with the Georgian Jews (also known as Gruzinim or Qartveli Ebraeli) and Beta Israel being most numerous at somewhat over 100,000 each. Many members of these groups have now emigrated from their traditional homelands, largely to Israel. For example, only about 10 percent of the Gruzinim remain in Georgia.

The Jewish communities of the modern world can all be found represented today in Israel, which is as much a melting pot as it is a salad bowl of different Jewish ethnic groups.

A brief description of the extant communities, by the geographic regions with which they are associated, is as follows:

Europe

The Caucasus and the Crimea

North Africa, Middle East, Central Asia

Jews originating from Muslim lands are generally called by the catch-all term Mizrahi Jews, more precise terms for particular groups are:

Sub-Saharan Africa

South and East Asia

Americas

Most Jewish communities in the Americas are descendants of Jews who found their way there at different times of modern history. The first Jews to settle in the Americas were of Spanish/Portuguese origin. Today, however, the great majority of recognized Jews on both the North American and South American continents are Ashkenazi, particularly among Jews in the United States. There are also Mizrahim and other diaspora groups represented (as well as mixes of any or all of these) as mentioned above. Some unique communities associated with the Americas include:

Israel

By the time the State of Israel was proclaimed, the majority of Jews in the state and the region were Ashkenazi. Following the declaration of the state, a flood of Jewish migrants and refugees entered Israel from the Arab world and the Muslim world in general. Most were Sephardim and Mizrahim, which included Jews from the Maghreb, Yemenite Jews, Bukharan Jews, Persian Jews, Iraqi Jews, Kurdish Jews, and smaller communities, principally from Libya, Egypt and Turkey. More recently, other communities have also arrived including Ethiopian Jews and Indian Jews. Because of the relative homogeneity of Ashkenazic Jewry, especially by comparison to the diversity of the many smaller communities, over time in Israel, all Jews from Europe came to be called "Ashkenazi" in Israel, whether or not they had any connection with Germany, while Jews from Africa and Asia have come to be called "Sephardi", whether or not they had any connection with Spain. One reason is that most African and Asian Jewish communities use the Sephardic prayer ritual and abide by the rulings of Sephardic rabbinic authorities, and therefore consider themselves to be "Sephardim" in the broader sense of "Jews of the Spanish rite", though not in the narrower sense of "Spanish Jews". Similarly "Ashkenazim" has the broader sense of "Jews of the German rite".

The founders of modern Israel, mostly Ashkenazi Jews, are often said to have believed themselves superior to these new arrivals. With higher degrees of Western-standard education, they were better positioned to take full advantage of the emerging Western-style liberal democracy and Western mode of living which they themselves had established as the cultural norm in Palestine during the pre-state era.

Cultural and/or "racial" biases against the newcomers were compounded by the fledgling state's lack of financial resources and inadequate housing to handle the massive population influx. Thus, hundreds of thousands of new Sephardic immigrants were sent to live in tent cities in outlying areas. Sephardim (in its wider meaning) were often victims of discrimination, and were sometimes called schwartze (meaning "black" in Yiddish).

Worse than housing discrimination was the differential treatment accorded the children of these immigrants, many of whom were tracked by the largely European education establishment into dead-end "vocational" schools, without any real assessment of their intellectual capacities. Mizrahi Jews protested their unfair treatment, and even established the Israeli Black Panthers movement with the mission of working for social justice.

The effects of this early discrimination still linger a half-century later, as documented by the studies of the Adva Center,[24] a think tank on social equality, and by other Israeli academic research (cf., for example, Tel Aviv University Professor Yehuda Shenhav's article in Hebrew documenting the gross underrepresentation of Sephardic Jewry in Israeli high school history textbooks,.[25] Every Israeli prime minister has been Ashkenazi, although Sephardim and Mizrahim have attained the (ceremonial) presidency and other high positions. The student bodies of Israel's universities remain overwhelmingly European in origin, despite the fact that roughly half the country's population is non-European. And the tent cities of the 1950s morphed into so-called "development towns". Scattered over border areas of the Negev Desert and the Galilee, far from the bright lights of Israel's major cities, most of these towns never had the critical mass or ingredients to succeed as places to live, and they continue to suffer from high unemployment, inferior schools, and chronic brain drain.

While the Israeli Black Panthers no longer exist,[25] the Mizrahi Democratic Rainbow Coalition and many other NGOs carry on the struggle for equal access and opportunity in housing, education, and employment for the country's underprivileged populace – still largely composed of Sephardim and Mizrahim, joined now by newer immigrants from Ethiopia and the Caucasus Mountains.

Intermarriage of all these regathered Jewish ethnic groups was initially uncommon, due in part to distances of each group's settlement in Israel, and cultural and/or "racial" biases. In recent generations, however, the barriers were lowered by state sponsored assimilation of all the Jewish ethnic groups into a common Sabra (native-born Israeli) identity which facilitated extensive "mixed-marriages".
